The “secret” hardware specifications of the iPhone 3GS where finally unveiled by dismantling the headset and were available on the internet just a few hours after the first iPhone 3GS was sold.

The new iPhone speed bump is supported by a new CPU (ARM Cortex A8) running 200MHz faster then its predecessor, and is also supported by a more powerful graphics chip: the PowerVR SGX and a much more generous amount of memory. The Ram was doubled from the already noteworthy 128MB of the original iPhone and iPhone 3G to 256MB.

Other changes, according to the iFixit staff, that filmed their own iPhone 3G S tear-down with the video camera on a second iPhone 3G S are reported below. Here is an overview of hardware specifications comparison between the original iPhone, the iPhone 3G and the new iPhone 3G S…

While the iPhone 3G apparently relied on an Infineon chip for its UMTS/HDSPA connectivity and video acceleration, the new model lacks such a chip. The Infineon iPhone 3G chipset was pointed to as the probable cause for the iPhone 3G connectivity issues. Apple has not acknowledged any problems, however, in the new iPhone 3GS no Infineon chip was discovered.

The extended battery life of the new iPhone 3GS is also worth noticing. The battery is is about 6% larger than the iPhone 3G’s battery.

Nearly all of the handset’s components have been relocated to the front side of the main logic board, including the Bluetooth, Wi-Fi, and Flash memory chips. An additional antenna connection near the dock connector was discovered. iPhone’s camera quality is much improved from the iPhone 3G. For example, close-up shots are now possible down to about 5 cm, and the brightness adjusted well when picking a focus area. Meanwhile, a test comparing the time it takes the Google Earth application to load reveals the new iPhone 3G S to be “bit faster than Apple’s claim of 2X speed improvement” over the iPhone 3G. The iPhone 3G’s oleophobic screen “does seem to clean slightly easier than the 3G’s normal screen,” according to the report.
